APR's Iridium Pro spark plug is spec'd at Heat Range 10 for these platforms, providing the correct thermal dissipation for modified applications where a warmer stock plug would risk pre-ignition.\u003c\/p\u003e\u003cp\u003eThe iridium electrode maintains a fine tip geometry for reliable, consistent ignition through thousands of heat cycles, resisting the electrode erosion that degrades spark quality and combustion efficiency on conventional plugs under high-load use. Heat Range 10 runs cooler than many OEM-spec plugs, appropriate for built engines where managing combustion chamber temperature is critical.
